NaN means Not-a-number (but for somehow normally its type is still a number :D )

If you do something like $$$\frac{0}{0}, \sqrt{negative}...$$$ then it returns $$$NaN$$$

String can also make $$$NaN$$$ value

    $$$0^0$$$ is $$$1$$$

    $$$x \over 0$$$ is $$$inf$$$

    but also, $$$0 \over 0$$$ is $$$NaN$$$
